What is it? Kilmainham Gaol is a fascinating former jail-turned-museum, and is yet another moving reminder of Ireland’s turbulent history. Throughout its 300 years of existence, it held everyone from members of the Irish Republican movement to straight-up murderers.
Why go? Considered by many a staunch symbol of Irish Nationalism, the Gaol now serves as an educational institute offering tours of its hallowed cells, chapels and grounds.
